One-time binding¶
Overview¶
Waits when an expression has a value (a non-undefined value), then stops watching. You need append ”::” in front of expression for using One-Time binding. It works with $watch, $watchText, directives and declarative bindings.
example¶
<div class="red {{::class}}"> {{::text}} </div>
<div al-show="::visible"></div>
<li al-repeat="it in ::list">...</li>
and so on
